The equivalent resistance (R_eq) of the parallel combination:

R_eq = (4 kΩ × 6 kΩ) / (4 kΩ + 6 kΩ) = 2.4 kΩ

The tolerance calculation:

Since both resistors have the same relative tolerance (10%), the resultant parallel combination will also have a tolerance close to 10%.

Explanation

To find the stored energy, we can use the formula:

Energy (E) = 0.5 × Capacitance (C) × Voltage² (V²)

Given:

C = 20 F

V = 200 V

E = 0.5 × 20 F × (200 V)²

= 0.5 × 20 × 40,000

= 400,000 J

Explanation

1/f = 1/v - 1/u

2.5 = 1/0.75 - 1/u

u = -0.26 m

So, the new near point is indeed:

0.26 m
